TO ALL WHOM IT MAY CONCISIRIT:l

Be it known that I, JAMES CONNOLLY, o f Boston, in the county of'Suiiolk, and State of Massachusetts, have invented an Improved Journal Box; and I do hereby declare that the following, taken inconnection with the drawings which accompany and form part of this specification, is a description of my invention suicient to enable those skilled 'in the art to practise it.

The invention relates ,to the construction of that class of journal boxes having oil reservoirs connected therewith, from which the lubricant is conveyed to the shaft by capillary attraction. The object of my invention is to provide such boxes with auxiliary chambers at each end, large enough for the shaftcollars to run in, cast integral with the box and oil reservoir, andcommunicating with or leading from the reservoir, so that any oil which drips or is thrown from the collars shall be conveyed back to the main body. of the lubricant. The invention consists, therefore, in a journal box, (having an oil reservoir forming part of it,) provided with extensions cast integral with thebox, in which extensions form enlarged chambers of suiiicien-t size-.for reception of the collars upon the shaft, which prevent longitudinal movement thereof, when said chambers communicate with or form part of the oil reservoir. The drawings represent a swinging journal box embodying my improvement, showing a, vieweot` the same, partly in eleva-tion 'and partly incentral section; B, a plan of the lower half' of the box; C, a cross-section on the red lines :v z and yy. a denotes the bearing; b, the babbiting thereof, o n which the shaft e runs; d, the oil reservoir, cast with the bea-ring, d; the space cored out between the reservoir and bearing containing the lubricant, which is fed up to one side -of the shaft, through a wicking, e, by capillary attraction. In this construction the kbox does not differ materially from vsome others; but the reservoir, d, is extended beyond each end ofthe box, and enlarged at such extensions, the cups f, formed by such extension and enlargements,

' communicating with or forming part of the main reservoir, through openings, h. Such extensions are cast integral with the box, and in the cups, f, formed thereby, the collars z', of the shaft c, run, the cups f being of sufficient size to receive without contact the lcollars t'. Over the box and cups, a cover c fits, keeping dust and dirt from the box and reservoir. The cups f serve to receive any oil which flows from the ends of the bearing, or whiclris thrown oT from or drops from the collars, and to convey it back to the reservoir; and by casting the box, the reservoir, and these cups or extensions, all in one piece, the box is made neat in appearance, and more cleanly, cheaper, and more compact than where the parts are cast separately.

I claimthe combination of the box or bearing, a, the reservoir d, and the enlarged extensions or cups, f, when of size suicient to receive and protect the shaft-collars z', and when cast in one piece, substantially as described.
